Built from high-speed steel (HSS) with a gold oxide coating, it offers improved lubricity and moderate wear resistance during threading operations. The plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for through-holes and moderately deep blind holes. At 2-15\/16 inches overall length with 4 flutes and an H3 thread limit, this tap suits precision threading work where controlled tolerance fits are required. Machinists, maintenance technicians, and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for general-purpose threading in ferrous and non-ferrous metals, plastics, and soft alloys. The 3\/8-24 UNF thread form is common in automotive, hydraulic, and mechanical fastening applications where a finer thread pitch is preferred over the coarser UNC standard. The straight flute design works best in through-hole applications and short blind holes where chips can be cleared from the bottom of the hole before they become an issue. It is well matched for both manual tapping with a tap wrench and use in CNC or manual drill press setups with appropriate tapping attachments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with right-hand thread direction for standard fastener applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) provides easy starting in through-holes and moderate blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction delivers hardness and heat resistance suitable for general-purpose threading\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and provides light corrosion protection during use and storage\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent tolerance control for close-fit threaded assemblies\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design offers strength and stability during the cutting operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight flute plug tap for any application requiring a 3\/8-24 UNF internal thread. Compatible with standard 3\/8-inch tap wrenches, T-handle tap wrenches, and tapping heads that accept the corresponding shank size for this tap class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreading operations should be performed by a qualified machinist or maintenance technician familiar with tap sizing and feed rates. Always use a compatible cutting fluid or tapping lubricant to extend tool life and improve thread quality. Ensure the workpiece is securely fixtured before beginning to tap. Never force a tap — back off periodically to break chips and clear the flutes, especially in deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20758\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51700930740530,"sku":"BDNA-20758","price":17.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b4af820189fea2b6fd73765b302215f.jpg?v=1788395467","url":"https:\/\/voomisupply.com\/products\/import-bdna-20758-straight-flute-tap-3-8-24-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
